TO ALL WHOM IT MAY CONCERN; Y

Be it known that I, GUSTAV L. JAEGER, of the city, county, and State of New York, have inventeda new and improved Fluid-Meter; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accom-- panying drawing, forming part of this specification, in which drawing- Figure 1 represents a longitudinal vertical section of this invention Figure 2 is a horizontal section thereof.

Similar letters indicate corresponding parts. l

This invention relates to a fluid-meter, the action of which is based on a wheel which revolves in a scroll or case, and carries an even number of hinged buckets, which are connected in pairs by cranksand rods, in such a manner, that, whenever one ofthe buckets strikes the closing edge of the scroll, said bucketis closed, and the bucket situated diametrically opposite thereto, and connected to it as above stated, is thrown open by a positive force, and that the fluid passing through the scroll acts on the wheel with thc least possible waste.

`The impurities which may be contained in the uid are prevented from passing into the bucket-wheel by a straining-faucet, provided with a mud-cisterna, and so arranged in the supply-channel that the iuid in its passage lto the measuring-wheel is compelled to pass through the mud-cistern and strainer of the faucet.

A represents the supply-channel, which leads to the measuring-wheel B, and thence to the discharge-channel C. Between the supply-channel and the measuring-wheel is the stop-`cock D, which is provided with a strainer, a, and with a mud-cistern, 6. When the stop-cock is turned to the position shown in fig. 1 of the drawing, the` lluid running in through the supply-channel is compelled'to pass through the mud-cistern and through the strainer, before it is allowed to come in contact with the meastiring-wheel.v By the action of the mud-cistern and strainer, all impurities which may be contained in the fluid are retained, and a correct operation of the measuring-wheel is insured. By turning the stop-cock tov such a position, that the opening c coincides with an aperture, 1Z,'in`thev bottom ot' the shell, the impurities contained in the mudcistern can be removed without permitting any waste of iluid, the supply-channel being closed whcn'the stop-cock is turned in the last-named position. l l i Y A handle, e, working between the 'two stops, ff', determines the position ofthe stop-cock., Y

The measuring-wheel, B, is fitted into a scroll,`E, which is composed of a small segment, g, fitting closely to the circumference ofthe wheel, and of a large segment, h, which allows the buckets z' to swing open, as shown in g. 1. lh'ese buckets are mountedon axlcs'which have their bearings in the rims of the wheel, and revolve freely therein, and on the ends of these axles are secured cranks k. The cranks of these buckets,twhich are situated diametri-cally opposite tojeach other, are connected by rods, l, which are curved or slotted, so that they clear the shaft ot' the wheel.

Whenever one of the buckets strikes the closing odge m of the scroll, said bucketis turned in, and at the same time the bucket connected to it by the rod l and cranks lr is thrown open by a direct force, so that the` iluid passing in through the supply-channel will act on said bucket, and cause the wheel to revolve in the direction of the arrow marked thereon in iig. 1. By this arrangement, the buckets are compelled to sweep in this position through the large segment h of the scroll, and very little', it' any, fluid is permitted to .pass the wheel without acting on the buckets, anl causing said whcclto redolve.

Having thus described my invention, what I claim as new, and desire to secure by` Letters Patent, is

1. lhe arrangement of the rnlul-cistern l) and 'strainer a in the. plug ofthe stop-cock D, substantially as and for the purpose described.

2. rl`he rolls Z und cranks k, connecting diametrically-opposite buckets of the wheel B, which rdns in the scroll Ebsubstautially as and for the purpose set forth. I
